Biological Effects of Radiation02:59

Biological Effects of Radiation

15.5K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

8.5K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Dosage Compensation

6.2K
In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with  distinct numbers of X chromosomes will...

X-linked Traits01:19

X-linked Traits

55.0K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Isotopes and Radioisotopes01:28

Isotopes and Radioisotopes

8.6K
In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.
An isotope containing...

Area of Science:

  • Radiation research
  • Sex differences in biomedical science
  • Radiological and nuclear applications

Background:

  • Sex is an underrecognized confounder in radiation research.
  • Knowledge gaps exist in understanding sex-specific effects in basic and translational research.
  • Implications for radiological and nuclear applications require further investigation.

Purpose of the Study:

  • To address the role of sex as a confounder in radiation research.
  • To examine sex differences in radiation animal models and their impact on medical countermeasure development.
  • To discuss biodosimetry, biomarkers, research representation, regulatory policies, and human health scenarios.

Main Methods:

  • A workshop was conducted with HHS-wide partners and stakeholders.
  • Discussions included academic investigators, industry researchers, and U.S. government representatives.
  • The workshop focused on scientific implications and knowledge gaps regarding sex in research.

Main Results:

  • Current study designs often lack the statistical power to analyze sex differences.
  • Underlying factors contributing to sex differences in radiation response are largely unknown.
  • Regulatory policies and drug/device development gaps were identified.

Conclusions:

  • Investigators must include both sexes in all research stages.
  • Accommodating sex differences ensures robust, reproducible, and accurate outcomes.
  • Addressing sex differences is essential for advancing public health in radiological and nuclear contexts.
